CUTTING-MACHINE.

SPECIFICATION forming part Of Letters Patent N0. 672,301, dated April 16, 1901.

Application filed October 5, 1899. Serial No. 732675- (No model.)

To (LZZ whom it may concern:

Be it known that LWILHELMUS ADRIANUS VAN BERKEL, manufacturer, a subject of the Queen of the Netherlands, residing at 68 Binnenweg, Rotterdam, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in Meat- Slicing Machines, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a side elevation, partly in vertical section, Fig. 2 a plan, partly in horizontal section, and Fig. 3 an end elevation, showing part of a meat-slicing machine having my improved knife applied thereto.

With the rotary circular knives of spherical or conical form heretofore employed in cutting or slicing machines good working is attained by causing the knife to come into contact at its beveled part only with the piece of meat, sausage, or the like to be cut, so that "it cannot become set fast at the cut-surface of the piece of meat or sausage. This effect is attained according to the present invention with a fiat knife or cutting-disk by arranging the said knife so that its axis of rotation is inclined obliquely to the plane of section of the meat, sausage, or the like. The knife or cutting-disk then works likewise with the beveled part only against the piece of meat,while the remaining surface of the knife is removed from the piece of meat.

Referring to the drawings, B is the table for supporting the meat, sausage, or the like, the edge B of this table forming the plane of section of the meat. The knife or cutting-disk O is mounted with its axis oblique to this plane of section in an oscillating arm A, so that only the beveled part 0 comes into contact with and acts on the piece of meat-for example, ata gradient of one in tenthe axis Z of the said arm A being arranged so that the edge of the said knife shall move closely along the edge B of the table B.

The arrangement for supporting the knife 0 in the arm A and imparting motion to the said knife is substantially the same as that described and shown in the Letters Patent granted me October 17, 1899, No. 635,225 that is to say, the shaft carrying the knife 0 is supported in suitable bearings in the arm A and is provided with a sprocket-wheel T,which is connected by a chain L to a sprocket-wheel T. The wheel T is connected by a springpawl s and ratchet-wheel s to a shaft 3, turning in the arm A and having a pinion 2 secured thereon and adapted to gear with a segmental rack 22, mounted on the frame R of the machine. By these means the knife can be caused to rotate as the arm A is depressed by means of the handle E, but remains sta tionary as the said arm is raised. In this case, however, the sprocket-wheels T T should be so arranged that the periphery of the Wheel T lies in the plane of the wheel T at the side thereof at which the chain is. tight, the slack side of the chain being at the side of the wheel T which diverges from the plane of the wheel T. The stretching-roller o is arranged at the slack side or limb of the chain and serves as a guide therefor.

It is'obvious that by arranging the axis of the knife 0 as above described a setting fast of the said knife in the piece of meat cannot take place, since the surface of the knife opposite thereto does not come into contact with the meat. By reason of the inclined or oblique position of the knife the cut-off disks or slices of meat or sausage are, however, not flat, but bent. By reason of the softness of the material, however, this is not of any moment. On the other hand, the arrangement has the advantage that the knife by reason of its flat form can be more easily made than the sphericalor conical knives heretofore employed.

What I claim is In a meat-slicing machine, the combination with a suitable bed or supportand an oscillating arm moving in a plane parallel to the end of said bed or support, of an obliquelymounted cutting-disk connected to said arm, and means for imparting a rotary motion to said obliquely-mounted disk.

In witness whereof I have hereunto set my hand in presence of two witnesses.
